Inuit mental health service utilisation in Manitoba: results from the qanuinngitsiarutiksait study

Despite decades of Inuit accessing services in Manitoba, Inuit-centric services remain scant and have only begun to emerge. This article reports on Inuit utilisation of mental health services in Manitoba. In this study, we focused on two interrelated cohorts: Inuit living in Manitoba and Inuit from the Kivalliq region who come to Winnipeg to access specialised services. We used administrative data routinely collected by Manitoban agencies. The study was conducted in partnership with the Manitoba Inuit Association, and Inuit Elders from Nunavut and Manitoba. Our results show that mental health-related consults represent between 1 in 5 and 1 in 3 of all consults made by Inuit in Manitoba. Rates of hospitalisation for mental health conditions are considerably lower than those of residents from the Manitoba northern health authority. Given that Nunavut has the highest rate of suicide in the world, our results suggest underserved needs rather than lower needs. Kivalliq and Manitoba Inuit utilise mental health services in Manitoba extensively, yet these services for the most part remain western-centric. Epistemological accommodations in the provision of mental health services have yet to be implemented. This is now the focus of our work.

Psychosis risk for lesbian, gay, and bisexual individuals: systematic review and meta-analysis

The social defeat hypothesis posits that low status and repeated humiliation increase the risk for psychotic disorders (PDs) and psychotic experiences (PEs). The purpose of this paper was to provide a systematic review of studies on risk of PDs and PEs among lesbian, gay, or bisexual (LGB) people and a quantitative synthesis of any difference in risk. PubMed, PsycINFO, Embase, and Web of Science were searched from database inception until January 30, 2024. Two independent reviewers assessed the eligibility and quality of studies, extracted effect sizes, and noted the results of mediation analyses. Using a random effects model we computed pooled odds ratios (ORs). Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. The search identified seven studies of PDs and six of PEs. As for PDs, the unadjusted (2.13; 95% confidence interval 0.72-6.34) and covariate-adjusted pooled OR (2.24; 1.72-3.53) were not significantly increased for LGB individuals. After exclusion of a study of limited quality, both the unadjusted pooled OR (2.77; 1.21-6.32) and the covariate-adjusted pooled OR (2.67; 1.53-4.66) were significantly increased. The pooled ORs were increased for PEs: unadjusted, pooled OR = 1.97 (1.47-2.63), covariate-adjusted, pooled OR = 1.85 (1.50-2.28). Studies of PE that examined the mediating role of several variables reported that the contribution of drug abuse was small compared to that of psychosocial stressors. The results of a study in adolescents suggested a protective effect of parental support. These findings suggest an increased psychosis risk for LGB people and support the social defeat hypothesis.

The risk of psychosis for transgender individuals: a Dutch national cohort study

BACKGROUND

The stressful minority position of transgender persons may result in a high risk of psychosis. Conflicting data suggest that the observed risk depends on setting of recruitment. We assessed the relative risk of non-affective psychotic disorder (NAPD) in a large, representative cohort of transgender persons.

METHODS

This cohort was composed using: data on legal sex change from the Dutch population registry and data on dispensing of cross-sex hormones (route 1), and a registry of insurance claims from mental health care including persons with a diagnosis of gender identity disorder (DSM-IV) or gender dysphoria (DSM-5) (route 2). They were matched by sex at birth, calendar year and country of birth to controls from the general population. Transgender persons (N = 5564) and controls (N = 27 820), aged 16-60 years at 1 January 2011, were followed until the first insurance claim for NAPD in 2011-2019.

RESULTS

The incidence rate ratio (IRR) of NAPD for transgender persons selected exclusively through route 1 (N = 3859, IRR = 2.00, 95%-CI 1.52-2.63) was increased, but significantly lower than the IRRs for those selected exclusively through route 2 (N = 694, IRR = 22.15, 95%-CI 13.91-35.28) and for those found by both routes (N = 1011, IRR = 5.17, 95%-CI 3.57-7.49; p value for differences in IRR < 0.001).

CONCLUSIONS

This study supports the social defeat-hypothesis of NAPD. The results also show the presence of a substantial number of transgender persons with severe psychiatric problems who have not (yet) taken steps to gender-affirmative care.
